JAMES BUSFIELD AND HENRY FELLOWS, OF HAVERHILL, MASSACHUSETTS, ASSIGNORS TO THE KENOZA SEAM PRESSING MACHINE COMPANY, OF

KINGSTON, NEW HAMPSHIRE.

SEAlVl-PRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No, 872,837, dated November 8, 1887.

Application filed April 14, 1887.

To all whom it may concern:

Be it known that we, JAMES BUSFIELD and HENRY FELLOWS, of Haverhill, in the county of Essex and State of Massachusetts, have in- 5 Vented certain new and useful Improvements in Seam-Pressing Machines, of which the following is a specification.

Our inventiomrelating to machines for pressing seams in the manufacture of boots and shoes and other leather-made articles, has for its object, first, an improved construction of the frame ofthe machine, whereby strength and rigidity of the several parts may be secured; second, an improvement in the means I for guiding the seam to be operated upon to the presser-rollers, whereby the seam may be opened or the edges separated and the seam otherwise properly prepared and presented to the presser-rollers to be operated upon; third, an improved construction and arrangement of the presser-rollers, whereby thoroughly effective and satisfactory results may be secured.

To these ends our invention consists in the improvements which we will now proceed to describe and claim, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming a part of this specification, the same letters indicating the same parts wherever they occur.

Of the drawings, Figure 1 represents a side elevation of a machine embodying our improvements, parts being pictured as broken out. Fig. 2 is a sectional end view. Fig. 3 is a detail view hereinafter referred to, Fig. 3 5 being a view,at a different angle,of one of the parts shown in Fig. 3.

The machine shown is an improvement upon that illustrated and described in application of Henry Fellows, No. 225,400, filed January o 24,1887, and,so far as the means for supporting and operating the lower resser-roller is concerned, need not be described in detail herein.

a represents the bed of the machine; I), the

4 5 overhanging arm; 0, the standard for supporting the same; and d, the standard for supporting the bearing rod or shaft for the lower presser-roller, 6. Experience has shown that the frame-work of machines of this class, as

Serial No. 234,807. (No model.)

heretofore constructed, is not sumciently rigid 0 rigidity of all parts of the frame, to all intents 6o and purposes perfect.

9 indicates the driving-pulley, fast on main shaft h, from which all of the parts are operated, a series of gear wheels and shafts (not shown, being the same as in the application before referred to) communicating a rotary motion from main shaft h to vertical shaft '5 on the front of the machine, rotatinggear i splined on said shaft 2', which gear meshes with another, i, fast on the journal-shaft of lower'presser-roller, 6, supported on the rod or shaft j, stepped upon a pad of rubber or similar material, j,

so as to be permitted to yield vertically when occasion requires. Lower guide, 6, is secured,

by means of ascrew, 6 to vertically-yielding shaft or rod j on a forwardly-projecting swell,

e", of said rod, as shown in Fig. 1.

k, Fig. 2, indicates a presser-wheel secured to main shaft h and v arranged over lower resser-roller, c, said rollers la and e being in quite the same relationship to each other as the upper and lower roller in the invention described in the aforesaid application.

1 indicates a gear-wheel secured to main shaft 11. alongside of roller 70, which gearwheel meshes with an idle-wheel, m, the latter in turn gearing with a toothed wheel, at, rigidly secured to the journal-shaft of a second upper presser-roller, 0, arranged opposite roller e to the rear of and at a lower horizontal o plane than roller 70, the journals of gear-wheels m n and roller 0 having bearings in a bracket projecting from the overhanging arm b.

1) indicates a seam-opening and guide roller j ournaled on the lower end of a rod, q, held 5 downward in its normal position by a spring,

8, in a manner similar to that in which the upper guide is supported in the invention dcscribed in the hereiubefore mentioned application. Said roller 1) is arranged to run in close juxtaposition to the upper face of guide 6, and is provided on the center of its periphery with a quite sharp V-shaped rib, 1', which is adapted to enter and run between the projecting edges of the seam and slightly separate them and turn them outward in p0- sition to be properly pressed down in passing between rollers e k 0.

tindicates a shoe extending forward from roller 1) to roller k, which shoe is provided on its lower face with a sharp V-shaped rib, t, similar to rib r on rollerp, which shoe and its described feature are designed to maintain the seam in the condition in which it leaves roller 11 until it enters between rollers e k.

a u represent two guiding fingers, preferably constructed of steel and fastened at their upper ends to a short stud or bracket projecting out from the support for rod 1. Said in gers a to depend in front of roller 1), and are adapted to receive between them the projecting edges of the seam and guide such seam with certainty to roller 1), the yielding properties of the fingers serving to let any unevenness in the seam pass without obstruction, and operating with the same effectin holding the edges of light and heavy seams in proper position.

It is obvious that seam-opening roller p may be used without guide-fingers u a or bridgingshoe t, or with the shoe t without fingers a a, or with the latter without the bridging-shoe.

2) indicates a lever pivoted at w to overhanging arm I), and at its forward end projecting under a lug, x, on rod q, and having a rod or cord, 3 attached to its rear end, which rod or cord may extend down to a treadle or like device (not shown) on the door, by which means the rear end of the treadle may be depressed, with the effect of raising rod (1 and its attached parts.

The operation of our invention may be briefly described as follows: The material to be operated upon is passed to the pressingrollers of the machine by depressing the rearward end of lever 11 and so raising seam-opening roller 1) and its adjuncts, when liberty to arrange the seam in proper position to be caught and carried through by rollers e will be afforded, the projecting edges of the seam being inserted between fingers uu, with the flange or rib r of roller 1) between such edges. With the material in this position, the machine is started, after first releasing lever 12,

with the result of carrying the seam through between rollers e k, which accomplish the preliminary pressing, and then between rollers e 0, which perform the finishing Work.

As shown, we prefer to cover the periphery of roller 0 with a band of vulcanized or semivulcanized rubber, 2.

We do not confine ourselves to the precise form and arrangement of parts shown, as these may be varied within the limits of mechanical skill without departing from the nature or spirit of the invention.

Having thus described our invention, what we claim is 1. In a seam-pressing machine, the combination, with seam-pressing rollers and a support or guide, 6, for the material, of seamopening roller 1), provided with a rib, r, and its yielding support q, as set forth.

2. In a seanrpressing machine, the combination, with seam-pressing rollers and a support or guide, a, for the material, of scamopening roller p, provided with a rib, 1', guidefingers u u, and a yielding support, q, for said seamopening roller and guide-fingers, as set forth.

3. In a seam-pressing machine, the combination, with seam-pressing rollers and a support or guide, e, for 'the material, of scamopening roller 1), provided with arib, r, bridging-shoe t, also provided with a rib, guidefingers u u, and a yielding support, q, for said seam-opening roller and guide-fingers, as set forth.

4. In a seam-pressing machine, the combination, with the lower positively-operated roller, 6, the main shaft, roller is thereon, gear Z, also secured to said shaft, idle-gear m, gear n, and roller 0, as set forth.

5. In a seam-pressing machine, the combi nation, with the seam-opening roller 1), guides u a, and yielding support q, for said opening roller and guides, said support being provided with the lug x, of the lever 12, pivoted to the frame and having one end extending under said lug x, as set forth.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, this 5th day of April, A. D. 1887.
